Product Description

 

High-Quality Mingtuo Vcb Vacuum Circuit Breaker 2 Poles, 73*72*80

Product Description

 
High-Quality Mingtuo Vcb Vacuum Circuit Breaker 2 Poles, 73*72*80

Working Principle:


When an overloaded circuit or short-circuit current occurs, the current sensor transmits the collected current signals to the intelligent controller.

The intelligent controller then issues a
trip command to energize the tripping coil, which releases the energy-stored spring in the operating mechanism.

This causes the contacts to rapidly separate,
extinguishing the arc.
